The Power of Newborn Genetic Screenings: How Newborn Genetic Screenings Can Change the Diagnosis

By Penelope Gatlin

October 2023

When our son was born in 2012, he was hypotonic, severely jaundiced, had feeding difficulties and features such as epicanthic folds and small low set ears. We were told immediately that doctors had suspicions of a genetic syndrome. At that time, genetic testing was limited and once abnormal karyotype, Trisomy 21, and Fragile X were ruled out, we left the hospital with an 8 day old and no diagnosis. While no testing was available at that time to identify the ultra-rare syndrome my child had, because it wouldn’t even be identified until 4 years later, I can only imagine the difference it would have made to our journey to have such an answer sooner. 

Instead, we were unprepared and actually unaware that just because a diagnosis hadn’t been made then that it didn’t mean there wasn’t in fact a rare disease present. Instead, we dealt with issues as they came and worried and wondered what would be next. From feeding issues and reflux and constipation, to low muscle tone and delayed walking, to speech delay, social and emotional delays, toileting delays, diagnoses of developmental delay, anxiety, situational mutism, sensory processing disorder, and autism, until finally genetic testing that revealed the diagnosis that we’d waited 7 years to find out. While receiving a diagnosis can seem scary, not having an answer but knowing there must be one is even more so. 

In 2019, the day I clicked onto the portal to see the test results, the largest word on the page was POSITIVE. My heart stopped for a second. For the first time, I read the words “Okur-Chung Neurodevelopmental Disorder.” A roller coaster of emotions ensued, including sadness that we hadn’t known this from birth because it would have made us as parents more prepared, and given us more understanding about what might arise next. Relief that we had an answer, grateful that this syndrome had been identified and that he was among one of the first hundred diagnosed with it in the world, and glad we had the privilege to have access to the testing. Excitement that we can participate in future research. Fright that there’s so much we don’t know about OCNDS, and happiness that there is something that we do. A feeling that we are no longer shooting in the dark and have a small but supportive community to rely on and learn from. I am hopeful that one day, all newborns with features like my child will be tested at birth, so parents can have access to the answers, support, and interventions and therapies that can best help their child as soon as possible.
